Abstract: An improved method of making a high heat transfer surface composed of metal mesh is described. The surface comprises multiple layers of wire mesh, stacked and laminated together by silver brazing. Advance in the state-of the-art is the novel manufacturing process designed to maximize heat transfer. Prior knowledge on manufacture of porous metal laminates has principally had as its purpose the filtration of particulate or control of hydraulic boundry-layer and made use of sintering techniques to solidify the elements. This invention optimizes the use of materials and process to accomplish maximum heat transfer.

Abstract: An improved display rack of any suitable material for articles of merchandise in containers which is formed of a plurality of spaced sets of concentric rods supported on an inclined base, which is distinctive in appearance and which permits self service with ensuing gravity feed of the containers toward the bottom of the rods.

Abstract: A label which may be removed intact from a container of materials and used as a cooking and serving vessel for the contents thereof, and methods of forming the same.

Abstract: An auto towing apparatus including an A-frame attachable to an auto for lifting and supporting a pair of the wheels thereof and having a socket for engaging a novel hitch ball and hoist combination on a towing vehicle, the hoist eliminating the need for precisely positioning the ball under the hitch socket.

Abstract: An efficient unit for placement on the exhaust cylinder of a dust collector, etc., the unit having a cylindrical filter through which the air passes and deposits dust thereon, the latter being removed by brushes for gravity deposit in an annular trough through which a scraper passes to move the dust particles to an exhaust tube.

Abstract: A plastic economical connection between toilet bowls and unaligned drain pipes which eliminates the conventional time consuming and relatively costly brazing or leading step required of the installing plumber, and which connection will readily fit the 3 or 4 inch diameter plastic pipes currently used by plumbers.

Abstract: A knee kicker which also incorporates means for intensifying the force of the blow to the carpet engaging head in carpet laying.

Abstract: Particular tooth assembly structure is presented for a trench digging machine powered to cyclically present a series of digging teeth as the machine moves forward to dig the trench. The teeth are shaped to produce a semi-circular trench bottom and each is of a size and length such that the power load for digging by each tooth is substantially evenly distributed.
